Note, the boat in this film is a prototype I built for a friend before finalizing the drawings on the KEP's FE-4S & 4SL Freebie's. So this boat have a turn-fin that is a bit too small = it makes it a bit difficult to keep it in lane #1 with the speed I know is there - one needs to nurse it a bit too much in the turns. Then the ski is a bit too narrow also creating a bit to much load on the motor as it penetrates the drink too much. But note, BOOTH of those items are adressed in the KEP's FE-4S & FE-4SL Freebie drawings.
